Writing CGI Programs in Python
And now for something completely different... Python has a very extensive, well documented and portable module library that provides a large variety of useful functions. The Internet-related collection is particularly impressive, with modules to deal with everything from parsing and retrieving URL's to retrieving mail from POP servers and everything in between.

In one of the examples on Page 6 "Putting it all together," the author uses a series of try:/except: as a DevShed reader noted this can be accomplished easier with the following syntax:
if form.has_key('email'):
email = form['email'].value
else:
email = ''
Or even this:
email = ''
name = ''
mapping = {
'email':email,
'name':name}
for m in mapping.keys():
if form.has_key(m):
mapping[m] = form[m].value
Although either one of these options would probably be a better alternative to the syntax used in the article's example, the example does give a correct example on how to use try:/except: properly.
